Homework Statement
the problem has height in cm, and density in g/cm^3. do i have to convert the gravity into cm/sec^2?
see below:
Homework Equations
pressure=(height in cm)(density in g/cm^3)(gravity in m or in cm?)
The formula for calculating pressure of a fluid is P = F/A, where P is pressure, F is force, and A is area.
To convert between different units when calculating pressure of a fluid, you can use conversion factors. For example, to convert from pounds per square inch (psi) to kilopascals (kPa), you would multiply the psi value by 6.894757 and then divide by 1.00 to get the equivalent value in kPa.
Yes, pressure of a fluid can be negative. This usually occurs when the fluid is under tension, such as in a vacuum or when a fluid is being pulled apart.
The depth of a fluid has a direct impact on its pressure. As depth increases, the weight of the fluid above also increases, resulting in higher pressure. This relationship is described by the equation P = ρgh, where P is pressure, ρ is the density of the fluid, g is the acceleration due to gravity, and h is the depth of the fluid.
Absolute pressure is the total pressure exerted by a fluid, including atmospheric pressure. Gauge pressure, on the other hand, only measures the pressure above atmospheric pressure. This means that gauge pressure can be either positive or negative, while absolute pressure is always positive.
